摘　　要：本文提出了以矢量控制、二重化方法、PWM方法三者结合起来改善SCR电流型变频器调速性能、消除转矩脉动的一种有效方法。文章对系统工作原理、输出波形和二重化PWM方法进行了理论分析和计算,并在此基础上对微机控制的原理和系统构成作了简要说明。实验结果表明,系统结构合理,消除转矩脉动的效果比较理想。This paper proposes an efficient method of improving the adjustable speed performance and eliminating the torque pulsations of a current source inverter (CSI) by combining the scheme of a dual connected current source inverter (DCCSI) with the vector control and the pulse width modulation (PWM) method. The system operation principle, output waveform, and the PWM method of DCCSI are theoretically analyzed and calculated. Based on that, the principle of microprocessor control and the system structure are briefly explained. The experimental results show that the system construction is reasonable and the effect of reducing the torque pulsations is satisfactory.
